Item 1.01 Entry into a Material Definitive Agreement.

Effective December 16, 2022, Perpetua Resources Idaho, Inc. (“Perpetua”), a wholly owned subsidiary of Perpetua Resources Corp. (the “Company”),

entered into an undefinitized Technology Investment Agreement (“TIA”) with the United States Department of Defense, Air Force Research Laboratory

(“DOD”) for an award of up to $24,800,000 under Title III of the Defense Production Act (“DPA”). The funding objective of the TIA is to complete

environmental and engineering studies necessary to obtain a Final Environmental Impact Statement, a Final Record of Decision, and other ancillary permits

to sustain the domestic production of antimony trisulfide capability for defense energetic materials at the Stibnite Gold Project. The DOD award is an

expenditure-based TIA whereby Perpetua may request reimbursement for certain costs incurred over the next 24 months related to environmental baseline

data monitoring, environmental and technical studies and other activities related to advancing Perpetua’s construction readiness and the permitting process

for the Stibnite Gold Project.

The TIA is subject to negotiation of a definitized agreement with the DOD. Until the agreement is definitized, the maximum funding available under the

TIA is capped at $18,600,000, 75% of the not-to-exceed amount. Perpetua expects to enter into a definitized agreement in the first half of 2023. However,

there is no assurance that Perpetua will be able to finalize the definitized agreement on the expected timeline or at all. The TIA contains customary terms and

conditions for technology investment agreements, including ongoing reporting obligations.

Item 7.01 Regulation FD Disclosure.

On December 19, 2022, the Company issued a press release announcing the TIA. A copy of the press release is furnished as Exhibit 99.1 to this Current

Report and incorporated herein by reference. Perpetua has applied for additional awards from the DOD under Title III of the DPA based on satisfaction of

certain milestones related to the Stibnite Gold Project. Perpetua has not received a decision with respect to the supplemental funding. There can be no

assurance that any additional funding will be provided or, if provided, the amount, timing and conditions of any such awards.

The information contained in this Item 7.01 and in the accompanying Exhibit 99.1 is being furnished and shall not be deemed “filed” for purposes of

Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be

NEWS RELEASE

December 19, 2022

Perpetua Resources Receives Critical Minerals Award of up to $24.8 million under the Defense Production Act

Perpetua receives Defense Production Act Title III funding to advance construction readiness, environmental baseline monitoring and environmental studies

as the Stibnite Gold Project continues through the permitting process

Stibnite Gold Project is poised to be the only domestically mined source of the critical mineral antimony, which is essential for national defense

BOISE, ID – Perpetua Resources Corp. (Nasdaq: PPTA / TSX: PPTA) announced today that its wholly owned subsidiary, Perpetua Resources Idaho, Inc.

(collectively, “Perpetua Resources” or “Perpetua” or the “Company”), was awarded a Technology Investment Agreement of up to $24.8 million under Title

III of the Defense Production Act (“DPA”). The funding objective of the Technology Investment Agreement, issued by the Air Force Research Laboratory, is

to complete environmental and engineering studies necessary to obtain a Final Environmental Impact Statement, a Final Record of Decision, and other

ancillary permits to sustain the domestic production of antimony trisulfide capability for defense energetic materials.

Antimony trisulfide is essential to national defense as a key component for munitions yet there is no U.S. mined supply. Perpetua plans to re-establish a

domestic supply of the critical mineral antimony as a by-product of one of the highest-grade open pit gold resources in the United States. The DPA funding

allows the Company to advance the construction readiness of the Stibnite Gold Project while the Company continues through the ongoing permitting

process, led by the United States Forest Service (“USFS”).

Under the funding agreement, Perpetua may request reimbursement for certain costs incurred over 24 months related to environmental baseline data

monitoring, environmental and technical studies and other activities related to advancing Perpetua’s construction readiness and permitting process for the

Stibnite Gold Project. The DPA funding does not interrupt the ongoing National Environmental Policy Act (“NEPA”) review process. The DPA award is

separate from the previously announced Small Business Innovation Research Phase 1 funding awarded to Perpetua by the Defense Logistics Agency in

September 2022.

“As Perpetua continues advancing our project through the permitting process, we are honored to enter this agreement to help advance our construction

readiness for future development,” said Laurel Sayer, President and CEO of Perpetua Resources. “Our vision remains unchanged, which is to redevelop a

world class gold deposit, provide the country with a critical mineral, and restore an abandoned brownfield site. Today, we continue to build momentum

towards turning our vision into a reality.”

Perpetua’s proposed Stibnite Gold Project, located in central Idaho, is in the sixth year of review under NEPA. The project is designed to restore

environmental conditions in the historic Stibnite mining district while responsibly redeveloping one of the highest-grade open pit gold resources in the U.S.

and becoming the only domestically mined source of the critical mineral antimony.

Perpetua expects that current cash resources, combined with the full DPA agreement, would provide the Company with sufficient liquidity to complete

permitting and early restoration activities on the current timeline as well as additional liquidity to begin advancing construction readiness.

“The Department’s DPA Investments Program is delivering on its core mission to restore domestic industrial capabilities essential to the national defense by

enabling the warfighter,” said Halimah Najieb-Locke, Deputy Assistant Secretary of Defense for Industrial Base Resilience. “This action reinforces the

Administration’s goals to increase the resilience of our critical mineral supply chains while deterring adversarial aggression.”

About the Department of Defense’s Defense Production Act Title III Program:

The Defense Production Act (the “DPA”) is intended to ensure that America has the resources, materials and technologies needed for national security. The

DPA Title III program is dedicated to ensuring the timely availability of essential domestic industrial resources to support national defense and homeland

security requirements now and in the future.

In order to qualify for funding opportunities under the DPA Title III, proposed projects must meet the following criteria:

· The industrial resource, material, or critical technology item is essential to the national defense

· Without Presidential action, United States industry cannot reasonably be expected to provide the capability for the needed industrial resource,

material, or critical technology item in a timely manner

· Purchases, purchase commitments, or other action pursuant to the DPA are the most cost effective, expedient, and practical alternative method for

meeting the need

About Perpetua Resources and the Stibnite Gold Project

Perpetua Resources Corp., through its wholly owned subsidiaries, is focused on the exploration, site restoration and redevelopment of gold-antimony-silver

deposits in the Stibnite-Yellow Pine district of central Idaho that are encompassed by the Stibnite Gold Project. The Project is one of the highest-grade, open

pit gold deposits in the United States and is designed to apply a modern, responsible mining approach to restore an abandoned mine site and produce both

gold and the only mined source of antimony in the United States. Further advancing Perpetua Resources’ ESG and sustainable mining goals, the Project will

be powered by the lowest carbon emissions grid in the nation and a portion of the antimony produced from the Project will be supplied to Ambri, a US-based

company commercializing a low-cost liquid metal battery essential for the low-carbon energy transition. In addition to the company’s commitments to

transparency, accountability, environmental stewardship, safety and community engagement, Perpetua Resources adopted formal ESG commitments which

can be found here.
